The fraction of voids occupied in the inverse spinel compounds are

The fraction of voids occupied in the inverse spinel compounds are

${\frac{1}{8}}^{th}$ of tetrahedral voids and $\frac{1}{2}$ of octahedral voids.
$\frac{1}{2}$ of tetrahedral voids and ${\frac{1}{8}}^{th}$ of octahedral voids.
${\frac{1}{4}}^{th}$ of tetrahedral voids and ${\frac{1}{8}}^{th}$ of octahedral voids.
${\frac{1}{8}}^{th}$ of tetrahedral voids and ${\frac{1}{4}}^{th}$ of octahedral voids.

Solution

The formula of inverse spinels is

{AB}_{2} O_{4}

. The

A^{II}

ions occupy the octahedral voids, whereas one-half of

B^{III}

ions occupies the tetrahedral voids and the other half occupies the octahedral sites.
